Just finished my ZEX Nitrous system install over the past weekend. Took about 3 days of 5-6hrs intervals each day. After completing my install I just wanted to share a few bits of advise that in hind sight would have benefited me greatly. Keep in mind that I am a relative novice when it comes to an install such as this. I know that some of this is probably very basic for a lot of the elder members out there. But in any case I imagine that there are a few individuals just like me out there so for those people here is some advice. First and foremost- Don't be cheap buy the necessary pieces/accesories upfront and it will save you time and headaches later. One highly recommended item is a Fuel line adapter. Included with my Zex kit was a fuel line T-tap which is in my opinon - is worthless- because once you cut into the fuel line and realize that they are plastic lined. Enough said - buy the fuel line adapter and save yourself hours of pain and punishment and you will also have a more reliable set up in that you won't have to worry about leaks or pressure issues. Colder spark plugs are also another essential piece of a good install. A few pieces that you will want to seriously consider are a safety blow down kit and a bottle warmer. My Second piece of advice is to completely read the directions in full and research other installer's experiences on the forum. There is a lot of good information available from people that have a really good job installing their kits and have good advise as well. I think that I printed out close to 200 pages of information before I started and it really came in handy in a few spots. Have an idea of what you are doing before you begin and it will help out immensly. Third item is to always mark, remeasure, mark again, remeasure and then cut or drill. The old adage is true - Measure twice, cut once. Fourth piece of advice is to know where you are running lines before you begin. Do a dry run so that once you start mounting up the equipement you have enough room and length to get everything installed correctly. There is nothing worse than having to go back to reinstall a line or a wire because it will not reach or is in the wrong place. Other than this here are a few parting pieces of advice- Wondering where to connect the TPS wire (White) from the ZEX controller box? I used the green wire on the back of the throttle body plug in the engine bay. Others have used the yellow wire on the top of the acclerator pedal inside the car. I'm sure there is an option through the ECU box but I did not go there. When running wires from the engine bay to the cabin I used a grommet in back of the battery that ran nicely behind the dash and allowed me to hide the wires up under the dash out of sight. By removing the fuse cover and the plastic shielding you can get to it pretty easy. When wiring in the ZEX activation power switch I went to Target and bought a cheap DC cigarette adapter, cut the plug off the end and wired it to the power wire. Now I didn't have to splice into any power sources but rather just plug it into the dash cig lighter when I want to arm the system. Be careful that you get a heavy duty adapter that will allow you to select different out currents. The one that I bought was $9.99 and was universal. Worked out very nicely. Anyway, I hope some of will help if you are thinking about installing a Nitrous kit in the near future.

a blow down tube connects to a pressure released side part of the bottle on the valve. in case of extreme heat the bottle has been known to explode. if you have this blow down tube, the bottle will not explode but it blows off the pressure released nozzle and drains all the nitrous down and out of the car safely....
Also sorry, I know some people have asked for pictures. For the most part it's nothing any different than everyone else has done. If anyone wants any close-up's or pictures of anything in particular let me know and I can do so and send them to you. Thanks
